Suggestions on a replacement HRM?

silhouettes

I am looking for a new HRM monitor. My old one the Polar F6 which I had awhile seems on it's last legs.

The things I am looking for in a new one are:

1. Polar (I know other brands and the bodybog, but I want another Polar)
2. Says calories burned, I know not all do.

and

3. If possible a distance timer. I am always curious how far I go how fast.. this isn't neccessary, but I'd like it.

I basically want an upgrade to my F6.

I do Jilian videos and run mostly for exercise. Not doing much strength just yet and no bike.

So suggestions?
